UV chamber for preconditioning test

In PV modules, a wide range of components are exposed to sunlight. The IEC 61215 standard therefore defines a UV preconditioning test (MQT 10) to verify whether these components can withstand the UV radiation of the sun.

Our UV preconditioning chamber enables simultaneous testing of two PV modules. UV radiation intensity is up to five times higher than that of natural sunlight, in order to accelerate the aging process as specified in the test procedure. During the test, the module temperature is maintained at a constant 60 °C within a dedicated temperature-controlled environment. Optionally, a high-temperature version –UVTC-HT – is avail­able, supporting module temperatures of up to 80 °C.

The system is delivered as a turnkey so­lution, including a data acquisition unit as well as integrated radiation and tempera­ture sensors. With the optionally available calibration set, customers have the opportunity to verify the intensity and quality of the UV radiation. Using the calibration function in the software, the calibration data is utilized to calculate the aver­age intensity and accumulated radiation dose with precision.
